Cím:Trends and hotspots in landscape transformation based on anthropogenic impacts on soil in Hungary, 1990-2018 / Balogh Szabolcs, Novák Tibor József
Dátum:2020
ISSN:2064-5031 2064-5147
Megjegyzések:The transformation of the landscapes due to the anthropogenic activities is increasing worldwide. These changes are also manifested in the change of soil-forming processes. The land cover (LC) changes evaluated according to their influence on anthropogenic features of soils allows to distinguish between LC changes result-ing increased and decreased human impact (HI). In our study, we assess the changes of HI on landscapes and its spatial distribution across Hungary. The changes were evaluated by using LC data of four periods between 1990 and 2018 reclassified based on the related anthropogenic soil features. To identify the hotspots of the changes 1?1 grids were applied in which the direction (increasing, neutral or decreasing HI) and frequency (number of landscape patches with LC changes) of changes were evaluated. In our research, the hotspots were identified over the studied four periods. We point out that the spatial distribution of hotspots is very differ-ent. The hotspots of the increased human impact are 2,449 cells (643.0 km2) between 1990 and 2018, and the most of it localized in the Pest Plain (67), Csepel Plain (64) and Nagykálló-Nyírség (60). Most of the multiple hotspots are in the outskirts of Budapest to Kiskunlacháza, Bugyi, Délegyháza. As we examine the decreasing hotspot data we found 1,679 cells (1,524.9 km2) between 1990 and 2018. In largest number, they occur on the Kiskunság Sand Ridge (38), Majsa?Szabadka Sand Ridge (37) and Nagykállói-Nyírség (36). Multiple hotspots are located in settlements Izsák, Ásotthalom, Vatta and Nyírmihályi. Regions with numerous hotspots require special management to moderate its negative consequences on soils to consider both increased anthropisation, but also extensification of land use and their consequences.

Cím:Soil erodibility calculations based on different particle size distribution measurements / Csaba Centeri, Zoltán Szalai, Gergely Jakab, Károly Barta, Andrea Farsang, Szilárd Szabó, Zsolt Bíró
Dátum:2015
ISSN:2064-5031 2064-5147
Megjegyzések:In this study we focused on the factors affecting final outputs of the USLE (Universal Soil Loss Equation) model. In doing so, we conducted soil particle size measurements in different institutions (University of Debrecen, University of Szeged and Geographical Institute, Research Centre for Astronomy and Earth Sciences of the Hungarian Academy of Sciences) with a variety of methodologies (laser, aerometer and pipette methods) onvarious soil materials (sandy, loamy and clay). Statistical analyses of the eight examined soil samples have been shown some signifi cant and some non-signifi cant differences among the particle size measurements. This paper is aimed at i) to ascertain whether these signifi cant differences in particle size measurements cause signifi cant differences in soil erodibility calculations; and ii) to assess the amount of soil loss calculated by these K factors. The results suggest that regardless of the relatively small percentage between the smallest and the greatest K factor values, the amount of soil loss can be fairly high, especially when erosion occurs ona longer or steeper slope. In the present case, when we compare simulations results, the amount of soil loss is more important than the difference in percentage between the minimum and maximum values. Because the percentage of the difference can remain the same between the simulations, while the amount of soil lossincreases way beyond soil loss tolerance limits.

Cím:Degree of human transformation of landscapes: a case study from Hungary / Csorba Péter, Szabó Szilárd
Dátum:2009
ISSN:2064-5031 2064-5147
Megjegyzések:CORINE land use categories were used to identify the scale of human impact on the landscapes. The test area covered 12 natural microregions in north-eastern Hungary (Figure 1). It was found that of the 12 microregions the oligohemerobe areas dominated in three, ?-euhemerobe in eight whereas ?-euhemerobe areas prevailed in one of them. The standard deviation value of the oligohemeroby data is the highest. There is not a single microregion in the study area with unfavourable landscape structure for ecotops from the aspect of human impacts. It is reasonable to weigh the different hemeroby levels. The dataset in Table 3 is the numerical representation of the degree of anthropogenic impacts when spatial ratios are taken into account. Adding up the weighed hemeroby values the degree of anthropogenic load on the landscape can be calculated. The resulting parameter can be called the hemeroby index (Table 5).

Cím:Application of a topographic pedosequence in the Villány Hills for terroir characterization / Szabolcs Czigány, Tibor József Novák, Ervin Pirkhoffer, Gábor Nagy, Dénes Lóczy; József Dezső, Szabolcs Ákos Fábián, Marcin Świtoniak, Przemyslaw Charzyński

Megjegyzések:Terroir refers to the geographical origin of wines. The landscape factors (topography, parent rock, soil, microbial life, climate, natural vegetation) are coupled with cultural factors (cultivation history and technology, cultivars and rootstock) and all together define a terroir. The physical factors can be well visualized by a slope profile developed into a pedosequence showing the regular configuration of the relevant physical factors for a wine district. In the present study the generalized topographic pedosequence (or catena) and GIS spatial model of the Villány Hills, a historical wine producing region, serves for the spatial representation and characterization of terroir types. A survey of properties of Cabernet Franc grape juice allowed the comparison of 10 vineyards in the Villány Wine District, Southwest Hungary. Five grape juice properties (FAN, NH3, YAN, density and glucose + fructose content) have been found to have a moderate linear relationship (0.5 < r2< 0.7) with the Huglin Index (HI) and aspect. Aspect, when determined on the basis of angular distance from South (180?), showed a strong correlation (r2 > 0.7) with FAN, NH3, YAN, sugar and density and moderate correlation with primary amino nitrogen (PAN). HI showed a correlation with three nitrogen related parameters FAN, NH3, YAN, density and glucose + fructose content. Elevation and slope, however, did not correlate with any of the chemical properties.

Cím:Spatial analysis of changes and anomalies of intense rainfalls in Hungary / Gergely Jakab, Tibor Bíró, Zoltán Kovács, Ádám Papp, Ninsawat Sarawut, Zoltán Szalai, Balázs Madarász, Szilárd Szabó

Megjegyzések:Extreme precipitation events can trigger flash flood, mass movements, pluvial flood and accelerated soil erosion. As soil structures are highly degraded due to intensive improper cultivation water infiltration can considerably decrease during the vegetation period. Additional changes in canopy coverage on the soil surface cause relevant variability in infiltration and hence vulnerability against runoff related disasters. Most researchers agree that the frequency of extreme precipitations increases, however, in the Carpathian Basin the uncertainties are quite high. This study aims to compare daily maximum mean precipitation amounts (MMPA) predicted by the Goda-method for June and August as the most probable months of extremities. We used the CarpatClim database as input and predicted MMPAs for two periods, 1960?1985 and 1986?2010. The Goda-method uses monthly data and calculates daily results on given probability. A general increase was found between the first and second half of the period regarding daily maximum precipitation amount in both investigated months. For August the 1-day precipitation amount increased from 56.1 mm to 61.8 mm, whereas 6-days amount from 93.8 mm to 103.2 mm at 1 per cent probability (r = 0.53; p < 0.001). Beyond this change, relevant spatial differences were found. Comparing the macro regions plains had lower increase compared to the mountains, whereas the highest increase was at the. The most endangered location is the southern part of the Transdanubian Hills where parallel with the intensive increase in MMPA both in June and August the environmental conditions such as loose parent material and the high percentage of crop fields also emphasize the potential hazard.

Cím:Distribution of landslides reconstructed from inventory data and estimation of landslide susceptibility in Hungary / Józsa Edina, Lóczy Dénes, Soldati Mauro, Drăguţ Lucian Daniel, Szabó József
Dátum:2019
ISSN:2064-5031 2064-5147
Megjegyzések:The complexity of landslides makes it difficult to predict the spatial distribution of landslide susceptibility and hazard. Although in most European countries the basic preconditions for the occurrence of mass movements (rocks and topography) have been mapped in detail, the triggering factors (e.g. precipitation or earthquakes) are much less predictable. A detailed nation-wide inventory for Hungary provides a unique base for landslide susceptibility mapping. As the methodology for the assessment the technique applied in the ELSUS 1000 project was selected. The micro-regions of Hungary were identified where mass movements contribute to land degradation. The paper provides a statistical evaluation of the distribution of landslides, depicts landslide susceptibility on maps and reveals the role of anthropogenic factors in the generation of mass movements. The mid-resolution elevation model (SRTM1), land cover data (CLC50) and surface geology database (Mining and Geological Survey of Hungary) allowed for the derivation of a landslide susceptibility map more detailed than before. Along with its background information the map reflects and explains the differences in landslide susceptibility among the individual hilly and mountainous regions.

Cím:A novel approach of mapping landscape aesthetic value and its validation with rural tourism data / Zsuzsanna Lontai-Szilágyi, Boglárka Bertalan-Balázs, Bernadett Zsiros, Mária Vasvári, Singh Sudhir Kumar, Patel Nilanchal, Katalin Martonné Erdős, Szilárd Szabó

Megjegyzések:Landscape aesthetic research that emerged from the second half of the 20th century has become increasingly appreciated and popular in the last few decades. There are two main reasons for this. On the one hand, it was recognized the role of landscape aesthetics in land use and environmental planning, management and conservation. On the other hand, its definition among Cultural Ecosystem Services has made it clear that landscape aesthetics has significant impact on human well-being and there is a need to examine it in the concept of Ecosystem Services and, in particular, Cultural Ecosystem Services (CES). The mapping of landscape aesthetics is mostly based on the exclusive evaluation of objective, biophysical landscape factors. The aim of the research was to create the landscape aesthetic map of Hungary with a novel method based on human perception. For this, a questionnaire survey and a GIS approach were used. In order to better understand the role of factors influencing the aesthetic value of the landscape, value maps separately for land cover and elevation that are decisive for the landscape experience were prepared. To validate the results of the maps, and contribute a better understanding of the interrelationship between CES, a certain tourism product was chosen, and the connection between landscape aesthetics and the offer of rural tourism was examined in Hungary and in the Danube Bend priority tourism development area. Our findings show that there is a difference in the results of the objective (GIS-based) and subjective (questionnaire-based) assessment of landscape aesthetic value with the more important role of elevation in the latter. According to our tourism product-based analysis, which represents a niche approach in its kind, landscape values are higher in the areas with rural accommodation. At the same time, based on the results of the Danube Bend region, it can also be concluded that elevation and land cover together are crucial factors in landscapes considered to be the most valuable in aesthetic terms. The most direct practical application of our research is to orientate further tourism development of the new Danube Bend area designated in 2017.

Cím:Industry 4.0 in a dualistic manufacturing sector : qualitative experiences from enterprises and their environment, Eastern Hungary / Nagy, Csongor; Molnár, Ernő; Kiss, Éva
Dátum:2020
ISSN:2064-5031 2064-5147
Megjegyzések:Industry 4.0 developing on the basis of digitalisation is gradually transforming production, the conditions of competition and relationships in global industry, affecting its interpretation and expanding its limits. This paper attempts to explore changing economic geographical context with the revaluation of comparative and competitive advantages in a semi-peripheral area of the EU. Based on company interviews, the effects of the new technologies of Industry 4.0 on the dual Hungarian manufacturing industry and its spatial structure are studied, and that whether they contribute to the reduction of duality and geographical polarization. In Eastern Hungary ? just like in most areas in East-Central Europe ? internationally competitive manufacturing companies emerged almost exclusively as a result of foreign direct investment, while domestic companies are forced into secondary or dependent roles. The empirical research has revealed significant differences in the progress of companies in Industry 4.0. Hungarian-owned companies evolve in a specific way from several aspects and face many difficulties. In contrast, enterprises with foreign interest continue to be the engine of development, driven from the "outside". Duality is also reflected in the corporate structure, in space and in the realisation of Industry 4.0.

Megjegyzések:Wind erosion is one of the most important land degradation processes in Hungary in the areas with low yearly precipitation values. The total land area suffering from wind erosion is approximately 10,000 km2 , 10 per cent of the country area. Observations and discussions on wind erosion and its negative impacts in Hungary started in the last century. Since the 1950s, scientists investigated wind erosion processes and their role in the evolution of alluvial fans in an integrative way, including laboratory measurements and field observations with respect to the stabilization and utilization of soils in agricultural areas. Since the late 2000s, there is an increasing demand worldwide to characterize the role of climate change and human activities in triggering land degradation processes. Studies have been conducted to investigate the mechanics, causes and control techniques related to wind erosion applying laboratory and field wind tunnel simulation tests and field observations. Some encouraging achievements have been made. In this paper we summarize the main research results of wind erosion research, and put forward some perspectives and suggestions on the problems of wind erosion research and control practices in Hungary.
